Activity of serum SOD and GSH-Px in tumor-bearing mice. To further understand the molecular mechanisms of action of ABGE against the MFC cell growth, we investigated the effects of ABGE on activities of antioxidant enzymes in tumor-bearing mice. Fig. 3A and B show the effect of ABGE on activities of SOD and GSH-Px in the serum. The analysis indicated that, compared with the negative control, ABGE significantly increased the activity of SOD and GSH-Px in a dose-dependent manner (p
